What are the application scenarios of indoor positioning technology?

This problem is relatively broad, because there are many indoor positioning technologies. Suggestions can clarify the types of technology and get better answers. We can first have a comparative understanding of the following types of technologies:

Generally speaking, positioning technology is distinguished by accuracy. The higher the accuracy, the higher the corresponding cost!

This kind of technology is often used in: warehouse inventory, on-the-job inspection, product traceability and other scenarios.

The second generation: coarse distance recognition, which can carry sensing information.

Active technologies, including WIFI, BLE, Zigbee, Sub 1G, Lora, etc. The positioning accuracy of the instrument can be achieved by RSSI and three-point positioning algorithm. The tag (terminal) is powered by battery, which can increase various interactive functions, such as key pressing, screen display, temperature and humidity detection, etc.

This technology is often used in: scenic spot explanation, indoor tracking, intelligent sensor monitoring, finding things to guide, finding people to guide, automatic attendance and so on.

The third generation: accurate positioning and ranging, mainly represented by UWB.

This paper mainly uses the technical characteristics of ultra-wideband to optimize the signal interference with ultra-short pulse signals. WEWILLS uses the time-of-flight algorithm, and the accuracy can reach 10cm. The disadvantage is that the current cost is not low enough, and it is mainly used in industrial fields, such as energy buildings (electric power, water conservancy, thermal power generation, etc. ), industrial intelligent manufacturing, personnel control of public security and judicial departments, tunnel construction (subway, high-speed tunnel, mine). At present, the technical solutions adopted by UWB manufacturers are consistent, and the biggest difference will be process service and landing experience.

This technology is often used in dangerous scene control, accurate attendance, dangerous work position monitoring, process efficiency analysis, fast and accurate tracing, valuable asset management and other scenes with high precision requirements.

According to the requirements of different application scenarios, the definition of accuracy will be different, such as many rooms in nursing homes. If the room needs to be determined, it can be realized by UWB, Bluetooth AOA, Bluetooth beacon, sub 1G, UHF, etc. (Of course, the difference in characteristics of each scene will determine the final technical selectivity). For example, if you need to know whether you are in bed, desk or toilet, you can basically only use UWB or Bluetooth AOA.

Generally speaking, indoor positioning is a big stage. WEWILLS is committed to an integrated platform and the integration of multiple technologies. End users only need to dock a set of API, and they can use single or multiple positioning technologies in different scenarios to achieve the desired results.
